Despite many signs pointing to a release of Google's presentation service at last week's Office 2.0 Conference (coverage), the only thing we got were some new tweaks to Docs and Spreadsheets that went largely under the radar. This morning, The Inquirer is claiming that things are stirring in the depths of Google's Mountain View headquarters, and the app is set to launch "any day now." They're also claiming that the app will be integrating technology from both of Google's slide show and presentation acquisitions Tonic Systems and Zenter, which the company bought … Read more

Despite the dream of an "ultimate handheld," it's really hard to get down to fewer than two portable devices. A Treo may do it all, but you still want an iPod; an iPhone is great, but you still need a BlackBerry for work; you like to listen to your iPod while playing your PSP or DS; and so on. Even those who do manage to get down to one super smart phone often have a Bluetooth headset to go along with it. And traveling with two devices means taking two power adapters along. Or at least it did--until the Belkin Dual USB Power Adapter came along. … Read more

Earlier this week, Advanced Micro Devices finally introduced the first true quad-core microprocessor in the PC market, code-named "Barcelona" and launched as part of AMD's Opteron line. David Kanter provided an excellent technical analysis of Barcelona on his Real World Technologies site.

Barcelona is not the absolutely fastest processor on the market. For single-core performance, both IBM and Intel offer faster chips. With multiple cores working, Intel and Sun can claim higher performance per socket--Intel because it can put two high-frequency dual-core chips in one socket, and Sun because it has an eight-core processor (the UltraSparc T2).

Although I'm sure AMD wishes it could claim those titles, there's another metric that matters even more to some customers. Barcelona delivers high… Read more

You can't accuse this robot of not having any heart.

A group of South Korean researchers from the Nano/Micro System Laboratory at Seoul National University has created a miniature robot powered by living heart tissue. The "microrobot" was designed to be injected into the human body and loaded up with a dissolving agent to clear blockages in arteries and other biological systems.

The scientists created the miniature robot by growing heart muscles from a rat on an elastic polymer called polydimethylsiloxane (PDMS).

As this video shows (AVI format), the robot scoots along on its three legs, … Read more

It looks like a giant version of the $2 styrofoam airplane toys you buy at the hobby shop, put together in two minutes, and render utterly useless after just a pair of overzealous throws. But this bird can soar.

So says its maker, the British defense contractor Qinetiq, which is crowing about the 54-hour flight turned in by its Zephyr High Altitude Long Endurance flyer. That's a record and then some for an unmanned aircraft, the company says, though it acknowledges the official word will still have to be delivered by the Federation Aeronautique Internationale.

And did we mention … Read more

One of the advertised improvements of the new PSP Slim was the fact that it could be recharged via its USB port. And while that may not sound like a major feature, for anyone who's ever traveled with a tangle of three, four, or even more AC adapters (laptop, phone, iPod, BlackBerry, ...), it was certainly an attractive idea. Unfortunately, it didn't quite deliver. Yes, the new PSP can be charged via its topside USB port, but the caveats involved make it more trouble than it's worth: the USB charging is almost twice as slow, only works when the PSP is powered on and in a dedicated USB charge mode, and it needs a PC as a source--it won't charge from a standalone AC-to-USB adapter. Thankfully, a handy accessory from Kensington provides a much better USB charging solution--and it works with both newer PSPs and the original models.… Read more

The winds of change are apparently upon us, quite literally, where alternative means of transportation are concerned. Just yesterday we wrote of a flying boat to come out of Brazil, for example, and now we learn of a trimaran that runs on kite power off the shores of Hawaii.

We're not talking about ordinary sails here, but high-tech kites that "harness higher winds above the water, reduce wetted surface with a lifting force, and improve hull stability," according to Maui-based Kite For Sail. The system, which provides far more propulsion than conventional sails, is meant to supplement … Read more

It's so difficult to maintain one's individualism these days. Car-boats, once at the top of the 007 cool meter, are hardly unique anymore. But there's still hope: Enter the "Flying Boat" from Brazil-based BRio.

It comes as a kit, which might seem kind of expensive at $10,000, especially because Gearfuse says the cost doesn't include the engine. Still, it's a fraction of what one of those new jet packs will set you back, and it promises to stay airborne longer than a minute.

Best of all, if the flying mechanism fails, you … Read more

Finavera Renewables, the Canadian company that wants to harness wind and wave power, has successfully deployed a prototype of its AquaBuoy 2.0 two and a half miles off the coast of Oregon.

Waves push the AquaBuoy up and down in the water. The motion puts pressure on a hydraulic fluid. The pressurized fluid then turns a turbine, which creates electricity. Wave and tidal power are primarily in the prototype and experimental stage, but several companies are ramping up prototypes and test vehicles. Marine Current Turbines hopes to put in a tidal turbine in the water off Northern Ireland later … Read more
